The Supreme Court on Friday dealt a loss to a group of gun rights groups and advocates seeking a temporary reprieve from the Justice Department's new ban on bump stocks.

The plaintiffs, which include five individuals and three gun rights groups, asked the court to block enforcement of the ban against them while their challenge plays out in court. Two of the court's conservative justices, Clarence Thomas and Neil Gorsuch, would have granted their request.

The Trump administration’s ban on bump stocks took effect March 26, though several pro-gun groups filed emergency requests asking the court to delay its implementation and enforcement while legal challenges continue. But in addition to Friday's action, the justices rejected two other requests last week.

The new regulation classifies bump stocks as machine guns, thus prohibiting their use and possession. Owners of the devices were required to destroy the devices or turn them in to law enforcement before the rule from the Justice Department took effect.

Those who do not comply with the ban could be charged with a felony and face up to 10 years and prison and a $250,000 fine.

Bump stocks allow semi-automatic rifles to fire more rapidly, and calls for a ban on the devices reached a fever pitch after the October 2017 shooting at a country music festival in Las Vegas. Fifty-eight people were killed, and scores more were injured when the gunman fired down at the crowd from the window of a nearby hotel.

Law enforcement found the shooter outfitted with dozens of firearms with bump stocks, and lawmakers subsequently demanded the devices be outlawed.

In February 2018, President Trump asked the Justice Department to ban bump stocks, and the agency announced the new rule in December.
